Materials Technology Division

Profile

Materials Technology Division deals with the development and the evaluation of the various materials used in the railway system. For that purpose we also examine the methods of the analysis necessary for understanding the mechanism of the phenomenon. Four laboratories below are working in their research field. And the division itself carries out the researches of environmental impact assessment of the railway system and new materials for railway.

Laboratories and their field

Concrete Materials

Concrete Material is researching and developing analysis, diagnosis, evaluation, and repairing technologies for degradational phenomenon of railway concrete structures such as elevated structures, tunnel lining, slab tracks, and poles.

Vibration-Isolating Materials

Vibration-Isolating Materials is in charge of polymeric materials such as vibration isolating material like axis spring rubber, floor material, materials for vibration suppression, soundproof, coating material for structures, and track pads.

Lubricating Materials

Lubricating Materials focuses on two fields: rolling bearings equipped with the running gears of railway vehicles, and lubricating oil and grease using for the rolling bearings, the driving device and the wheel/rail contact areas.

Frictional Materials

Frictional Materials is researching and developing materials and systems for railway-specific contact boundaries such as rails/wheels, wheels/brakes and catenaries/pantographs.
